Grasshoppers have an elongated body with long hind legs used for leaping. They are distinguished from crickets and katydids by antennae shorter than their bodies and their short ovipositor (needle-like organ for laying eggs at the tip of the female’s abdomen). Some grasshoppers have a drab body with more colorful hindwings revealed in flight. Males are smaller than females. Among grasshoppers are locusts, which occasionally group in large swarms, causing extensive crop damage.
